Invited for this issue's Front Cover is the research led by Renewable Energy Lab from Pusan National University (South Korea). The cover picture shows ternary alloy oxide composed of NiCeWOx as advanced bi-functional electrocatalyst anion membrane full water splitting. efficient HER-OER electrocatalytic performance attributed to its unique alloyed oxygen vacancy structure-property, which facili...

In this paper, some properties of the periodic shadowing are presented. It is shown that a homeomorphism has the periodic shadowing property if and only if so does every lift of it to the universal covering space. Also, it is proved that continuous mappings on a compact metric space with the periodic shadowing and the average shadowing property also have the shadowing property and then are chao...

Heterogeneous catalysis plays a central role in the chemical and energy fields, owing to high tunable activities of solid catalysts that are essential achieve favorable reaction process efficiency, their ease recycle reuse. Numerous research efforts have been focused on synthesis towards obtaining desired structure, property catalytic performance. The emergence development microfluidic reactor ...

The neuroprotective property of quercetin is well reported against hypoxia and ischemia in past studies. This property of quercetin lies in its antioxidant property with blood-brain barrier permeability and anti-inflammatory capabilities. µ-Calpain, a calcium ion activated intracellular cysteine protease causes serious cellular insult, leading to cell death in various pathological conditions in...

High-throughput experimental methodologies are capable of synthesizing, screening and characterizing vast arrays of combinatorial material libraries at a very rapid rate. These methodologies strategically employ tiered screening wherein the number of compositions screened decreases as the complexity, and very often the scientific information obtained from a screening experiment, increases. The ...

Abstract Depletion of fossil fuels resources has triggered more research on finding potential alternative sources that are sustainable such as biomass waste. However, deconstruction the complex waste into desired products is too challenging and usually require a strong catalyst with great hydrolysing property. Common acids sulphuric acid, hydrochloric acid nitric were most studies for conversio...

Enterobacter cloacae strain 96-3 nitroreductase (NR) is a homodimeric flavoenzyme that catalyzes the pyridine nucleotide-dependent four-electron reduction of a variety of nitroaromatic compounds, including the explosives TNT (2,4,6-trinitrotoluene), RDX (1,3,5-trinitro-1,3,5-triazine), tetryl (2,4,6-trinitrophenyl-N-methylnitramine), and pentryl (2,4,6-trinitrophenyl-N-nitroaminoethylnitrate). ...

In the current study, a convenient and simple way is presented to synthesize a novel type of supported heterogeneous organocatalyst in 21-81% yield by the copolymerization of 9-amino-9-deoxy-epi-cinchonine organocatalyst with acrylonitrile using AIBN as radical initiator. The chemical compositions (x/y) and weight-average molecular weights of copolymers 1a-d were determined by (1)H NMR and GPC ...
